1、附录Car rear parking brake is well known characteristics and maintenanceparking brake, the car must have one of the braking device. Iveco second-generation products in vehicle brakes, parking brake is a mechanical control mechanism and the rear drum brake combination. Such a structure, so that not onl
2、y after the brake drum brake and parking brake also played a role. With the use of rear disc brake, Turin-V vehicle parking brake with the rear brakes will be fixed in the form and change. If the rear wheels with drum brakes, while maintaining the basic structure of the original second-generation pr
3、oducts; the use of a disc brake, rear wheel will have to configure a dedicated parking brake. On the disc brake is concerned, there is the structure with the parking brake disc brake, the parking braking force acts on the brake discs on both sides of the work surface, such a brake complex structure,
4、 relatively somewhat less reliable. Turin-V cars equipped with dual-piston sliding front disc brakes have specifically set up after the parking brake. The role of the parking brake force to the brake drum inner disk on the work surface, so that the brake disc has two separate friction surface, life
5、can be improved, brake caliper is also simplified the structure. Turin-V car rear parking brake device manipulated by a mechanical parking brake and special climate of two parts (brake disc for the traffic, shared parking brake parts.) 1, mechanical control mechanism to maintain the basic structure
6、of the original second-generation products, mainly composed of pieces with a handle, the first wire cable, ratchet plate, adjust the threaded sleeve, locking nut, after the wire cable and the guide disc and so on. 2, the special structure and principle of the parking brake disc brake after the match
7、 with a special parking brake, parking brake after the special bottom bracket through eight holes, and the rear axle relative to the fixed axle shaft flange bolts. Before and after the friction shoe upper and lower ends are pulled tight against the return spring on the role of regulation under the p
8、ull pin and arm in the middle and the bottom through the active support underwriting phase. Slide the gear on the pin on the regulator can adjust the elongation or shortening the length of sales to adjust the friction inside the shoe and drum brake disc space. Role in pulling arm, it is subject to m
9、anipulation after the wire cable, when the pull the handbrake lever, the role will be the central axis of the pin pulling arm as a fulcrum, the friction shoe before and after distraction, so that the drum with an effective brake disc friction torque, and thus play a role in the private parking brake
10、 parking brake in the brake plate bracket, and another two holes for the installation of rear brake clamp assembly. After the band drum and wheel brake disc will be Yi, after the special parking brake, brake caliper assembly, and so orderly together. 3, special parking brake after the decomposition
11、and synthesis in vehicle rear wheels when the removal of the Yi, a number of components such as rear brake disc, you can special parking brake on the decomposition and synthesis, the basic process steps are as follows: From the front Bu friction shoe, remove the return spring, spin off the short len
12、gth adjustment, remove the friction between the support shoe underwriting folder, you can remove the friction shoe. Remove the branch underwriting, Hou Lasuo loose parking brake pull arm connected with the role, remove the effect of the second arm pull the wheel speed sensor mounting bracket removed
13、, you can remove the sensor. Remove the axle casing under the flange and the eight mounting bolts, then remove the parking brake bottom bracket. according to the requirements of the drum brakes on the parts removed for cleaning checks, abandoned exceeded the difference of wear parts. synthesis by de
14、composition of the reverse steps. After synthesis, measured with a vernier caliper before the hind piece diameter, while toggle adjustment pin 1, the diameter value than 1720 , a small 0.4 1 mm. After the adjustment of parking brake parking brake because the brake after the non-automatic compensatin
15、g clearance, the use of a period of time, the brake gap will gradually increase, reflecting the tension in the handle spine when the number of teeth affected, will exceed the number of (normal number of teeth affected 4 6), which will affect the rear wheel in vehicle performance. To this end, prompt
16、ly after the parking brake adjustment. Adjusted as follows: from the top rear of the car, and to support the frame bracket, then remove the rear wheels; Loosen the parking brake cable adjusting screw lock nut sets; Remove the top long after the parking brake hole rubber plug, the use of special tools (99,372,249) toggle adjustment pin gear, so that before and after the friction shoe distraction, resulting in hand can not turn the plate so far; loos
