Description
Technical field
The present invention relates to the automotive brake technical field, specifically is a kind of floating caliper type disc centre brake with automatic resetting mechanism.
Background technique
Along with the variation of modern offroad vehicle equipment, the deadweight of vehicle itself continues to increase, and security requirement improves constantly, and the vehicle braked performance requirement is also increasingly high.At present, offroad vehicle central authorities floating caliper type disc centre brake is dawdled because of rear brake shoe and is caused the parking braking Problem of Failure outstanding, and the mean distance between failures that how to improve parking braking is an important topic in the industry.The friction plate return spring that former Parking Brake carries; After removing parking braking; Back friction plate can't overcome mechanical friction power and the moment between caliper body and sliding pin, causes the back friction plate to be close on the parking braking dish taking place the braking phenomenon of dawdling, and dawdles and directly causes the wearing and tearing too early of back friction plate and increase the parking braking gap; After this gap increases to above Parking automatic backlash adjustment range, just cause parking braking to be lost efficacy.Existing break mean distance between failures is 500Km, poor reliability.
Summary of the invention
The objective of the invention is a kind of floating caliper type disc centre brake of dawdling and causing parking braking to lose efficacy and design because of the centre brake rear brake shoe for eliminating with automatic resetting mechanism.
Technological scheme of the present invention: the floating caliper type disc centre brake of band automatic resetting mechanism of the present invention comprises the centre brake caliper body; The pitman arm shaft and the rocking arm that are connected with the centre brake caliper body pass the sliding pin of centre brake caliper body, sliding pin support; Be installed in front brake lining and rear brake shoe on the centre brake caliper body; Central brake disc between front brake lining and rear brake shoe, braking ejector pin assembly, preceding brake pad return spring; On the rear end of centre brake caliper body and the sliding pin between the sliding pin support, be with pressure spring; On the centre brake caliper body, stretch out a limiting board, the adjustable clearance stop screw is installed on the limiting board, the sliding pin support at the corresponding pressure spring of the rod end of adjustable clearance stop screw place.
Rectangular seal is established at the two ends of sliding pin in the centre brake caliper body.
Fit between described original state adjustable clearance stop screw and the sliding pin support.
The axis of described adjustable clearance stop screw and the parallel axes of pitman arm shaft.
The coaxial line of described adjustable clearance stop screw and sliding pin.
Advantage of the present invention: the present invention has guaranteed in the driving process that brake shoe separates with brake disc before and after the Parking, has guaranteed that the gap of front brake lining and rear brake shoe and central brake disc is balanced, and brake shoe can not cause the phenomenon of dawdling before and after making.Reach and eliminate eccentric wear and the phenomenon of dawdling.Increase rectangular seal at former caliper body pin-and-hole two ends, avoid in the vehicle using process, impurity such as sand and dust, muddy water get into and cause caliper body stuck, the brake shoe phenomenon of dawdling before and after causing.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Further specify the present invention below in conjunction with accompanying drawing and embodiment.
Fig. 1 is a structural representation of the present invention: the floating caliper type disc centre brake of band automatic resetting mechanism of the present invention comprises centre brake caliper body 1; Pitman arm shaft 2 that is connected with centre brake caliper body 1 and rocking arm 3 pass the sliding pin 4 of centre brake caliper body 1, sliding pin support 5; Be installed in front brake lining 6 and rear brake shoe 7 on the centre brake caliper body 1; Central brake disc 8 between front brake lining 6 and rear brake shoe 7, braking ejector pin assembly 9, preceding brake pad return spring 10; On the rear end of centre brake caliper body 1 and the sliding pin 4 between the sliding pin support 5, be with pressure spring 11; On centre brake caliper body 1, stretch out a limiting board 13, adjustable clearance stop screw 12 is installed on the limiting board 13, the sliding pin support 5 at the corresponding pressure spring of the rod end of adjustable clearance stop screw 12 11 places.
Described original state, when promptly not braking, brake disc 8 is fitted between adjustable clearance stop screw 12 and the sliding pin support 5 when gap between front brake lining 6 and the rear brake shoe 7 equates.Generally, the gap between front brake lining 6 and rear brake shoe 7 and the brake disc 8 changes at 0.5～1mm.
The parallel axes of the axis of described adjustable clearance stop screw 12 and pitman arm shaft 2.
The coaxial line of described adjustable clearance stop screw 12 and sliding pin 4.
Working principle: after removing parking braking,, a gap is arranged with central brake disc 8 because front brake lining 6 is drawn back in the effect of front brake lining 6 return springs 10; If the effect of return spring 10 is excessive, rear brake shoe 7 possibly be attached on the central brake disc 8, causes rear brake shoe 7 that the phenomenon of dawdling takes place to brake on the parking braking dish; If the effect of return spring 10 is too small, the phenomenon of dawdling (this is the problem that existing technology exists) possibly take place to brake in front brake lining 6 on the parking braking dish.The present invention is with pressure spring 11 on the rear end of former centre brake caliper body 1 and the sliding pin 4 between the sliding pin support 5; After removing parking braking; The resistance that pressure spring 11 overcomes 4 of centre brake caliper body 1 and sliding pins makes centre brake caliper body 1 return, and rear brake shoe 7 also can leave 8 one gaps of central brake disc, thereby guarantees in the driving process; Brake shoe separates with brake disc before and after the Parking, reaches to eliminate eccentric wear and the phenomenon of dawdling.
The effect of position-limit mechanism is that the effect of limit compression spring 11 power makes centre brake caliper body 1 return.When brake caliper body 1 return of centre; When the gap that rear brake shoe 7 leaves central brake disc 8 reaches 0.5～1mm; Receive stopping of adjustable clearance stop screw 12, stop motion, the elastic force of adjustable clearance stop screw 12 limit compression springs 11; Guaranteed that front brake lining 6 and rear brake shoe 7 are balanced with the gap of central brake disc 8, brake shoe can not cause the phenomenon of dawdling before and after making.Adjustable clearance stop screw 12 can be regulated gap between front brake lining 6 and rear brake shoe 7 and the brake disc 8 and be provided with and resemble.
Adopt rectangular seal 14 to avoid in the vehicle using process, impurity such as sand and dust, muddy water get into and cause caliper body stuck, the brake shoe phenomenon of dawdling before and after causing.
