Description
Technical field
The utility model relates to a kind of automobile parking braking parking brake driving device.
Background technology
At present, the front wire drawing of automobile parking braking parking brake is directly connected on pull bar conventionally, and this connection mode makes the transmitting ratio of automobile parking braking parking brake very little, causes some vehicle hydraulic parking brake to feel heavy, effort.In addition, after the arc of existing automobile parking braking parking brake, wire drawing mounting groove is normally fixed on pull bar, can not be by regulating the position of wire drawing mounting groove after arc make its adapt to the rear wire drawing of different length, and pull back spring is fixed on and on pull bar, also makes the length of pull back spring and elastic force to regulate.
Summary of the invention
It is little that the purpose of this utility model is to overcome automobile parking braking parking brake transmitting ratio, and the defect such as that parking brake is felt is heavy, effort, provides a kind of automobile parking braking parking brake driving device.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of automobile parking braking parking brake driving device, wire drawing mounting groove, pull back spring after comprising pull bar and being located at the arc on pull bar, also comprise mounting bracket, torque arm, described mounting bracket is provided with bearing pin, described torque arm is provided with axle sleeve, and described axle sleeve and bearing pin are hinged, and the movable end of described torque arm is provided with front wire drawing mounting groove, the middle part of torque arm is provided with pull bar mounting hole, and one end of described pull bar is connected with pull bar mounting hole.
Distance between described front wire drawing mounting groove and axle sleeve and the ratio of distances constant between described pull bar mounting hole and axle sleeve are 1.1～2: 1.
Described pull bar is screw rod, and after described arc, the both sides of wire drawing mounting groove are passed pull bar and are fixed on pull bar by the nut being located on pull bar.
On described pull bar, be also provided with fixed cover, described fixed cover is located at after arc between wire drawing mounting groove and nut.
On described fixed cover, be also provided with hook sheet, one end of described pull back spring is connected on hook sheet.
Because the masterpiece of front wire drawing and rear wire drawing is different for the position in torque arm, the distance ratio that is bearing pin from S. A. is separately amplification ratio, so the utility model can amplify parking brake transmitting ratio effectively, more easily laborsaving while making to pull parking brake; Adopt screw rod as pull bar, and on pull bar, establish nut and fixed cover, can easily wire drawing mounting groove after arc be fixed on to the diverse location on pull bar, thereby make wire drawing mounting groove after arc be applicable to the rear wire drawing of different length; On fixed cover, establish hook sheet and pull back spring is connected on hook sheet, thus just can be by regulating the position of fixed cover to regulate length and the elastic force of pull back spring.The utlity model has simple in structurely, feature is installed, easy to use etc.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the structural representation of mounting bracket in the utility model;
Fig. 4 is the structural representation of torque arm in the utility model.
In figure: 1-mounting bracket (1a-bearing pin), 2-torque arm (wire drawing mounting groove, 2c-pull bar mounting hole before 2a-axle sleeve, 2b-), 3-pull bar (3a-nut, 3b-fixed cover, 3c-hook sheet), wire drawing mounting groove after 4-arc, 5-pull back spring.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is elaborated.
Embodiment: as shown in Fig. 1～4, a kind of automobile parking braking parking brake driving device, wire drawing mounting groove 4 after comprising pull bar 3 and being located at the arc on pull bar 3, pull back spring 5, also comprise mounting bracket 1, torque arm 2, described mounting bracket 1 is provided with bearing pin 1a, described torque arm 2 is provided with axle sleeve 2a, described axle sleeve 2a and bearing pin 1a are hinged, the movable end of torque arm 2 is provided with front wire drawing mounting groove 2b, the middle part of torque arm 2 is provided with pull bar mounting hole 2c, one end of pull bar 3 is connected with pull bar mounting hole 2c, distance A between described front wire drawing mounting groove 2b and axle sleeve 2a and the ratio of the distance B between described pull bar mounting hole 2c and axle sleeve 2a are 1.25: 1.Described pull bar 3 is screw rods, and after described arc, the both sides of wire drawing mounting groove 4 are passed pull bar 3 and are fixed on pull bar 3 by the nut 3a being located on pull bar 3.On described pull bar 3, be also provided with fixed cover 3b, described fixed cover 3b is located at after arc between wire drawing mounting groove 4 and nut 3a, is also provided with hook sheet 3c on fixed cover 3b, and one end of pull back spring 5 is connected on hook sheet 3c.
During use, first the utility model is fixed on vehicle body by the bolt hole on mounting bracket 1, then front wire drawing is connected to front wire drawing mounting groove 2b in torque arm 2 upper, rear wire drawing is connected to revolver and rear right wheel after automobile through wire drawing mounting groove 4 after arc and by two ends.
