Description
Technical field
The utility model relates to vehicle brake technical field, in particular to a kind of disc brake with floating caliper.Meanwhile this reality
With a kind of novel vehicle for further relating to application disc brake with floating caliper.
Background technique
Brake is with the dress for making moving component (or movable machinery) deceleration, stopping or keep the functions such as halted state
It sets.Disk brake is one kind of vehicle brake, including disc brake with fixed caliper and disc brake with floating caliper.
Disc brake with floating caliper is in braking process, and on piston pressing friction piece to brake disc, the effect counter-force of generation exists
Caliper can be made to have the fraction of displacement along brake disc axial direction during eliminating idle stroke and pressing friction piece backboard.Due to braking
The rotatory inertia of disk will drive friction plate and generate tangential displacement, and friction plate backboard and tong holder is made to screw out end in contact, friction plate backboard
Suffered tangential force can be transmitted on tong holder and generate brake force.In addition, caliper is solely subjected to axial tension in braking process, to rubbing
The full state of wear of pad, caliper have biggish axial displacement.To prevent motor turning operating condition lower clamp caused by by lateral force
It drags power and taps abnormal sound, general there are two types of solutions.
Scheme one: chute-type floating clamp, guide pin of the axial displacement of caliper at caliper trunnion are constrained, and guide pin is logical
It crosses bolt to connect with caliper, pin hole is opened on tong holder, pin and pin hole clearance fit.The effective length of guide pin about 50-60mm,
The full state of wear of brake block also has 2/3 guide pin length and pin hole to cooperate；Under damped condition, piston and claw are pressed in friction
On piece backboard, friction plate and brake disc, braking disc spins drive friction plate to be resisted against tong holder unscrewing end, suffered by friction plate
Frictional force, which is transmitted on tong holder, generates brake force.Under steering situation, general rubbing by guide pin and pin hole, friction plate and tong holder
It wipes power and overcomes lateral force suffered by caliper.
This chute-type floating clamp, due to shape of product complexity, the machining accuracy of pin hole and guide pin is higher, and pin hole must first turn
Hole is reamed again to improve the precision of pin hole, and pin hole depth is deeper, and to improve wearability, guide pin needs to carry out at surface
Screw thread is managed and processes, processing technology is more, and the components such as bolt, rubber boot, amount of parts are also needed in assembling process
It is more, assemble cumbersome, higher cost
Scheme two: plug-type floating clamp, tong holder and caliper lean on pin connection, are a difference in that guide pin is fixed with chute-type floating clamp
On tong holder, pin hole is opened on caliper, and guide pin length is shorter, about the half of chute-type floating clamp.Under damped condition, piston
On claw pressing friction piece to brake disc, the rotation band movable friction plate of brake disc generates tangential displacement, as severity of braking increases
Add, friction plate and tong holder screw out end in contact, and power suffered by friction plate, which is transmitted on tong holder, generates brake force.To prevent road conditions of jolting
Lower clamp is reversed along X-axis and impact noise, is fastened at caliper claw with spring and tong holder, limits caliper radial displacement；Turn to work
Under condition, lateral force suffered by caliper is overcome to be provided jointly by the guide pin of inside, the spring force in outside and friction plate.
This plug-type floating clamp, friction plate do not have yoke spring buffering, and when brake is easy to produce the knock of friction plate and tong holder,
Fixed spring fastens tong holder and caliper, and the resistance to sliding of caliper is larger, will be added with the tong holder and caliper of friction plate cooperation
Work, amount of parts is more, and assembly process is more, higher cost, and the fixed spring at claw has the risk fallen.
