Abstract
The utility model belongs to the technical field of vehicle braking and particularly relates to a mechanical disc parking braking device which comprises a speed changing box arranged on a vehicle body. An output shaft end of the speed changing box is connected with a transmission shaft. A braking disc is arranged between the output shaft end and the transmission shaft. A braking caliper matched with the braking disc is arranged above the braking disc. The braking caliper is connected with a transmission lead screw and is matched with the transmission lead screw in a threaded mode. The transmission lead screw is connected with a hand brake pulling wire. The hand brake pulling wire is pulled, the transmission lead screw is driven to rotate, and accordingly the two arms of the braking caliper move towards the middle portion to clamp the braking disc, the transmission shaft is locked, and the purpose of parking is achieved. According to the mechanical disc parking braking device, a mechanical braking mode is used, parking stability and reliability can be greatly improved, structure is simple, and production cost is low.
Description
Technical field
The utility model belongs to the vehicle brake technology field, is specifically related to a kind of mechanical type video disc locking device for a vehicle.
Background technique
In the existing parking braking, common employing drum brakes, drum brakes has the ironcasting of the similar tambourine of a shape, is called brake drum, and it and tire are fixed and are rotated with speed.Disk type brake has preferable reactivity and stable, and thermal diffusivity is preferable, changes advantages such as easy.The absolute braking force height of drum brakes is used in the trailing wheel of pony car morely.But its water rate is higher, and therefore whole cost is higher simultaneously.
The brake drum of drum brakes can increase at the back diameter that is heated, and causes the stroke of stepping on braking pedal to strengthen, and the brake reaction takes place easily not as the situation of expection.Therefore when driving the vehicle that adopts drum brakes, avoid brake continuously to cause brake block Yin Gaowen and produce the heat fade phenomenon as far as possible.In addition, the drum brakes system response is slower, brake to trample power wayward, be unfavorable for making high-frequency brake, simultaneously, drum brakes complex structure component are more, braking gap need adjust, inconvenient maintenance.
The model utility content
The purpose of this utility model is to propose a kind of mechanical type video disc locking device for a vehicle, can effectively solve the deficiency that the high frequency brake is unstable when adopting drum brakes, maintenance difficulty is high and cost is high.
To achieve these goals, the technological scheme that adopts is:
Mechanical type video disc locking device for a vehicle, include gearbox, be arranged on the car body, the output axle head of described gearbox is connected with transmission shaft, between described output axle head and transmission shaft, be provided with brake disc, the top of this brake disc is provided with the braking clamp adaptive with described brake disc, this braking clamp be connected with turn-screw and with this turn-screw screw-thread fit, described turn-screw is connected with the parking brake backguy.
The utility model has the advantages that:
Compare with drum brakes, the mechanical type video disc locking device for a vehicle that reaches described in the utility model, not sealing, the fines of brake wearing and tearing can not be deposited on the brake disc, the centrifugal force of disk type brake can outwards be dished out pollutants such as all water, dust, has guaranteed the cleaning surfaces of locking device for a vehicle.
Each component is independent outside in the video disc locking device for a vehicle, is easier to maintenance than drum brakes.In addition, because mechanical type video disc locking device for a vehicle is the mechanical type brake, thereby its Parking is stable and reliability can improve greatly, and simple in structure, cost of production is lower.
Description of drawings
Fig. 1 is the structural representation of mechanical type video disc locking device for a vehicle in the utility model;
Fig. 2 is the A portion enlarged view among Fig. 1;
Fig. 3 is a side view of brake disc among Fig. 1;
Wherein, the 1-gearbox, 2-exports axle head, 3-transmission shaft, 4-brake disc, 5-braking clamp, 6-turn-screw, the backguy of 7-parking brake.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:
Extremely shown in Figure 3 in conjunction with Fig. 1, mechanical type video disc locking device for a vehicle, include gearbox 1, be arranged on the car body, the output axle head 2 of this gearbox is connected with transmission shaft 3, between output axle head 2 and transmission shaft 3, be provided with brake disc 4, the top of brake disc 4 is provided with braking clamp 5, and is suitable with described brake disc, and brake disc 4 is between 5 liang of arms of braking clamp, when braking clamp two arms move to the centre, can and brake disc form friction, and then reach the purpose of Parking, described braking clamp 5 be connected with turn-screw 6 and with this turn-screw screw-thread fit, this turn-screw is connected with parking brake backguy 7, the backguy of pulling parking brake makes turn-screw rotate, and then drive braking clamp two arms move the clamping brake disc to the centre, lock transmission shaft 3, reach the purpose of Parking.
Compare with drum brakes, the mechanical type video disc locking device for a vehicle that reaches described in the utility model, not sealing, the fines of brake wearing and tearing can not be deposited on the brake disc, the centrifugal force of disk type brake can outwards be dished out pollutants such as all water, dust, has guaranteed the cleaning surfaces of locking device for a vehicle.
Each component is independent outside in the video disc locking device for a vehicle, is easier to maintenance than drum brakes.In addition, because mechanical type video disc locking device for a vehicle is the mechanical type brake, thereby its Parking is stable and reliability can improve greatly, and simple in structure, cost of production is lower.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model also is not limited to above-mentioned giving an example; should be noted that; those skilled in the art is under the instruction of this specification; any change of having done, variation or replacement form all drop within the essential scope of the present utility model, ought to be subjected to protection of the present utility model.
