Cheng Zhong, the lateral surface of the outer ring of bearing, the i.e. left side of left bearing 6-1, right bearing 6-2 right side be pressed against each elastic layering
On 5 free end 5-2, exerted a force by left and right bearing to elastic layering 5.In the present embodiment, bullet is driven using the extruding of bearing 6
Property press strip 5 deform, left and right bearing can synchronize extruding be located at left and right brake disc medial surface two groups of elastic layerings 5, make
Left and right brake disc can synchronous braking, and braking effect stablize.
In order to drive two bearings are synchronous to squeeze elastic layering 5, the pushing mechanism further includes for driving bearing along institute
The forks arm 7 of the sliding of shaft 2 is stated, the lower end of forks arm 7 is between a pair of bearings, the upper end of forks arm 7 and hydraulic cylinder or gas
The piston of cylinder pressure connects, opposite or backwards to moving by the driving of hydraulic cylinder or pneumatic cylinder.The crossover sites rotation of forks arm 7 is matched
Together on rotating dog 8, two lower ends of forks arm 7 are suitable for pressing up against the interior of the inner ring of left bearing 6-1, right bearing 6-2
Side, i.e. the two of forks arm 7 lower end press up against the right side of the inner ring of left bearing 6-1 and the inner ring of right bearing 6-2
Left side on.Since the lower end of forks arm 7 is pressed against on the inner ring of bearing, and the outer ring of bearing 6 is pressed against elastic layering 5
On, forks arm 7 is not interfered with when the rotation of lock pin 4, left and right brake disc and elastic layering 5, the position of forks arm 7 can be fixed
It is motionless.
On the basis of above-mentioned one kind durable holding brake device, a kind of vehicle is resistance to including wheel and described one kind
Holding brake device, the durable holding brake device of described one kind are mounted on wheel.
The working principle of the utility model is as follows:
When needing parking braking, the piston of hydraulic cylinder or pneumatic cylinder pushes two upper ends of forks arm 7 to be moved away from, and pitches
Two lower ends of shape arm 7 are also moved away from and open, synchronous to push left bearing during two lower ends of forks arm 7 are opened
6-1, right bearing 6-2 promote elastic pressure along 2 dorsal glide of shaft, the synchronous free end 5-2 for squeezing elastic layering 5 of left and right bearing
Item 5 deforms, and the elastic layering 5 of deformation squeezes spring 12, drives the lock pin 4 being firmly connected with it along through-hole 3 by spring 12
It slides in and out to setting length, lock pin 4 is made to protrude from the lateral surface of corresponding left and right brake disc, pass through the system that outside is fixed
Dynamic friction block prevents lock pin 4 from rotating, and then brakes left and right brake disc, final brake wheel.When the wheel of stopping is due to external force
(such as on ramp, vehicle is glided due to gravity), left brake disc 1-1 and right brake disc 1-2 when acting on and rotating
It rotates with it, to make the lock pin 4 on disc rotate, when lock pin 4, which encounters the braking brake pad on the outside of disc, to be stopped, due to bullet
The flexible deformation of spring 12, lock pin 4 at this is since the extruding of braking brake pad retracts in through-hole 3, and the outer end of remaining lock pin 4 is then
It is all stretched out out of through-hole 3, since braking brake pad fixation will not rotate on the brake, so when lock pin 4 encounters drag friction
When block, braking brake pad can prevent lock pin 4 from continuing to rotate, to prevent left and right brake disc and vehicle wheel rotation.
When needing to release parking braking, the upper end of hydraulic cylinder or pneumatic cylinder driving forks arm 7 moves towards and resets, and pitches
The lower end of shape arm 7 also moves towards, and elastic layering 5 resets under the action of own resilient, and the outer end of each lock pin 4 bounces back again
To through-hole 3, lock pin 4 and braking brake pad are without touching, to relieve prevention of the braking brake pad to lock pin 4, lock pin 4 can be with
Left and right brake disc normal rotation, parking braking release.
When lock pin 4 stretches out, if its length for stretching out left and right brake disc is enough, lock pin 4 can encounter the system of brake
Dynamic pincers, just replace above-mentioned braking brake pad to realize braking action by caliper.Since the intensity and hardness of caliper are bigger,
So as to play more stable braking action.
The holding brake device of the utility model is not necessarily to be used for the drum brake system of parking in the installation of the outside of brake disc,
The space on the outside of brake disc is saved, makes the brake disc lateral surface of same diameter that there is the bigger contact surface with braking brake pad
Product, the conventional brake power for cooperating corresponding braking brake pad that can make rear-wheel are bigger.
The utility model realizes parking braking in the way of lock pin 4 and braking brake pad or with the locking of caliper,
The reliability of braking is higher using the frictional force brakes between brake drum and brake-shoe more in the prior art, when automobile is parked in abrupt slope
When upper, the frictional force between the brake drum and brake-shoe of the prior art is not enough to overcome the descending power of automobile, can make the vehicle of automobile
Wheel still rotates, and the device of the utility model will not then turn a wheel, and parking braking effect is more preferable.
The utility model guarantees that lock pin 4 is encountering drag friction using the retractility and more stable screen resilience of spring 12
When block, can compressed spring 12 and be maintained in through-hole 3, spring 12 compared to flexible elastic layering 5 have it is wider range of
Stroke and more longlasting, more stable elasticity, to keep the persistence and durability of whole device.
Particular embodiments described above, to the utility model solve the technical issues of, technical scheme and beneficial effects into
It has gone further description, it should be understood that the foregoing is merely specific embodiment of the utility model, and has not had to
In limitation the utility model, within the spirit and principle of the utility model, any modification, equivalent substitution and improvement done
Deng should be included within the scope of protection of this utility model.
