The application is directed to a kind of increasing friction force in braking, plays booster action to the brake apparatus of vehicle in itself, makes vehicle
Fast braking.
Utility model content
The utility model provides a kind of vehicle brake auxiliary device, increasing friction force when being braked for vehicle, makes vehicle
Brake as early as possible, the utility model is achieved through the following technical solutions:
A kind of vehicle brake auxiliary device based on double frictional contact surfaces, including brake frame, brake frame comprise at least two
Transverse arm, a brake axle for being used to install friction pulley and a crossbeam for being used to install hydraulic cylinder are provided between two transverse arms;
Friction pulley is fixed on vehicle chassis positioned at one end of two transverse arms, the other end of two transverse arms away from friction pulley, stretches out liquid
The expansion link of cylinder pressure is fixed on vehicle chassis, and hydraulic cylinder is connected by oil pipe with the oil tank of vehicle, by oil pump by oil tank
Hydraulic oil be pumped into or pump out in hydraulic cylinder.
Hydraulic oil in oil tank is pumped into hydraulic cylinder rapidly by car running computer control oil pump, and brake frame is fallen, friction pulley and ground
Face CONTACT WITH FRICTION;The hydraulic oil in hydraulic cylinder is pumped into oil tank by car running computer control oil pump after vehicle is brought to a halt so that brake
Frame lifts.
There is the projection of frictional force between increase and ground on brake friction wheel outer surface, there is increasing on brake friction pulley inner surface
The groove of frictional force greatly between brake axle.
There is the projection of frictional force between increase and brake friction pulley, the projection and table in brake friction pulley on brake axle outer surface
The fit depressions in face.
Preferably, friction pulley is rubber wheel, the model DP/GYCD of hydraulic cylinder, the model 80YHCB-60 of oil pump.
The utility model has the advantages that:
The utility model increased servicing unit on the basis of vehicle driving braking, by increasing capacitance it is possible to increase friction during braking
Power, vehicle is forced to be braked as early as possible, the projection for the wheel outer surface that rubs increases the frictional force on friction pulley and ground, friction pulley inner surface
Groove and the projection on brake axle surface be engaged, increase the frictional force of friction pulley inner surface and brake axle outer surface, make to rub
The friction beneficial to braking all occurs for its surfaces externally and internally when wiping wheel rotation, double frictional contact surfaces is realized, with conversion consumption vehicle as early as possible
Kinetic energy, have the function that shorten vehicle braking distance, vehicle is stopped as early as possible.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples:
Fig. 1 shows the structure of brake frame.
Fig. 2 shows that hydraulic cylinder is fixed on the structure of vehicle chassis with brake frame.
Fig. 3 shows the structure of friction pulley.
Embodiment
Presently in connection with accompanying drawing, the utility model is described in more detail.Schematic diagram of these accompanying drawings as simplification,
Only illustrate basic structure of the present utility model in a schematic way, therefore only show the composition relevant with the utility model.
As shown in figure 1, a kind of vehicle brake auxiliary device based on double frictional contact surfaces, including brake frame 1, brake frame 1
Including at least two transverse arms 102, a brake axle 101 for being used to install friction pulley 2 and one are provided between two transverse arms 102
For installing the crossbeam 103 of hydraulic cylinder 3.
As shown in Fig. 2 friction pulley 2 is positioned at one end of two transverse arms 102, two transverse arms 102 away from friction pulley 2 it is another
End is fixed on vehicle chassis, and the expansion link for stretching out hydraulic cylinder 3 is fixed on vehicle chassis, and hydraulic cylinder 3 passes through oil pipe 6 and vehicle
Oil tank 4 connect, the hydraulic oil in oil tank 4 is pumped into or pumped out in hydraulic cylinder 3 by oil pump 5.
Friction pulley is rubber wheel, the model DP/GYCD of hydraulic cylinder, the model 80YHCB-60 of oil pump, and oil pump passes through row
The control of car computer automatically controls.
As shown in figure 3, there is the projection of frictional force between increase and ground, the inner surface of friction pulley 2 on the outer surface of friction pulley 2
The upper groove with frictional force between increase and brake axle 101.Have on the outer surface of brake axle 101 between increase and friction pulley 2
The projection of frictional force, the projection and the fit depressions of the inner surface of friction pulley 2.
Specific work process and operation principle of the present utility model are:
Hydraulic oil in oil tank is pumped into hydraulic cylinder by car running computer control oil pump, and hydraulic cylinder is extended by oiling rear telescopic rod,
Because expansion link one end is fixed, therefore force brake frame earthward close, fall one end with friction pulley, friction pulley connects with ground
Touch simultaneously rolling friction.Because friction wheel outer surface is provided with projection, so as to increase the frictional force with ground;Furthermore in friction pulley
The groove on surface and the projection on brake axle surface are engaged, and further increase rubbing for friction pulley inner surface and brake axle outer surface
Wipe power.In friction wheel from rotation, its surfaces externally and internally all rubs, and double frictional contact surfaces is realized, with conversion consumption vehicle as early as possible
Kinetic energy, have the function that to shorten vehicle braking distance, vehicle is braked as early as possible.After vehicle braking, car running computer control oil pump will
Hydraulic oil in hydraulic cylinder is pumped into oil tank, and hydraulic oil is reduced so that expansion link shortens in hydraulic cylinder so that brake frame is lifted
Rise, auxiliary brake effect terminates.
