Automotive brake is one of component of automobile active safety, carries out forced deceleration or parking, i.e. service brake for making the automobile in traveling according to the requirement of driver.Or, for making to stop the automobile travelling (be included in ramp) under different kinds of roads condition steadily halt, i.e. parking braking.
Fig. 1 to Fig. 4 shows a kind of disc type brake assembly embodiment that the utility model provides.
As can be seen from Fig. 1 and Fig. 2, this Disk brake apparatus comprises fitting seat 4, brake disc 2, first break 1 and second brake 3.
Described fitting seat 4 is fixedly linked, for other component provide suitable mounting structure and mounting point with vehicle bridge.
Described brake disc 2 is with alloyed steel manufacture and be fixed on wheel, with vehicle wheel rotation, is the fricting couple piece of disk type braker.In order to meet the requirement of braking ability, described brake disc 2 possesses higher strength and stiffness, friction factor high and stable as far as possible, and suitable wear resistance, heat resistance, thermal diffusivity and thermal capacity etc.
Described second brake 3 carries out forced deceleration or parking (service brake) for making the automobile in traveling according to the requirement of driver.Described first break 1 is fixed vehicle under halted state for vehicle, prevents vehicle because of external force slip (parking braking).Described second brake 3 and described first break 1 all act on described brake disc 2, realize braking function by producing friction torque with the interphase interaction of described brake disc 2.
For the ease of assembling and installation, described second brake 3 and described first break 1 are arranged at same fitting seat 4.Described fitting seat 4 is fixedly installed in vehicle bridge.Particularly, one end of described fitting seat 4 is applicable to connecting described brake disc 2, the other end is applicable to being connected with vehicle bridge, the first link 41 and the second link 42 arranged near described brake disc 2 is also provided with between the two ends of described fitting seat 4, described first break 1 is fixed on described first link 41, and described second brake 3 is fixed on the second link 42.
Further, described first link 41, second link 42 includes two connection handles, and each described connection handle forms tapped hole, and described first break 1, described second brake 3 are all bolted on described connection handle.
Described first break 1 is disc brake with floating caliper, acts under the driving of park brake operation device (such as mechanical parking brake or electronics parking brake).Please refer to Fig. 3, this disc brake with floating caliper comprises U-shaped first braking clamp body 11 be installed on described fitting seat 4, and described first braking clamp body 11 can slide axially along described brake disc 2 on this fitting seat 4.Wherein this first braking clamp body 11 is provided with first piston 12 in the side of described brake disc 2.This first piston 12 end is provided with the first brake slipper 13, correspondingly, described first braking clamp body 11 being positioned at described brake disc 2 opposite side is provided with second brake slipper 14 relative with described first brake slipper 13.
During braking, described first piston 12, under the effect of hydraulic coupling, pushes described first brake slipper 13 to described brake disc 2.It is mobile along described brake disc 2 axial (Fig. 3) to the right that the reaction force acted on described first braking clamp body 11 promotes described first braking clamp body 11, and the second brake slipper 14 be fixed on described first braking clamp body 11 is pressed against on described brake disc 2.So described first brake slipper 13 and described second brake slipper 14 of described brake disc 2 both sides clamp described brake disc 2, make it to produce the friction torque stoping brake disc 2 to rotate, realize braking.
Described second brake 3 is disc brake with fixed caliper, acts under the driving of driving brake operating device (service brake).As can be seen from Figure 4, described disc brake with fixed caliper comprises U-shaped second braking clamp body 35 being fixedly installed in fitting seat 4, this second braking clamp body 35 is relatively set with two pistons in described brake disc 2 both sides---the second piston 31 and the 3rd piston 34, and two-piston end is provided with brake slipper, be respectively the 3rd brake slipper 32 and the 4th brake slipper 33.During braking, described second piston 31 and described 3rd piston 34 push described brake disc 2 to simultaneously, and described 3rd brake slipper 32 and described 4th brake slipper 33 press against on described brake disc 2, clamp described brake disc 2, produce the friction torque stoping brake disc 2 to rotate, thus realize braking.According to its principle, disc brake with fixed caliper comparatively disc brake with floating caliper has retro-speed soon, and the advantage that braking moment is large, is therefore used to service brake.
As another kind of implementation, described second brake 3 adopts disc brake with floating caliper equally, and described second brake 3 and described first break 1 are fixedly installed in same fixed base.The piston of described second brake 3 and the piston of described first break 1 are oppositely arranged in described brake disc 2 both sides.
In order to prevent having an impact between two kinds of breaks, ensure braking ability, relative to described brake disc 2 spin axis, the angle between described second brake 3 and described first break 1 is greater than 60 °.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.And thus the apparent change of extending out or variation be still among the protection domain that the utility model creates.
