Abstract
The utility model discloses a parking braking maneuver mechanism, which comprises a control arm and a stroke output board which can be connected with a parking braking pull rod, and further comprises an inner main body mounting plate and an outer main body mounting plate. One end of the control arm is hinged with the inner main body mounting plate and the outer main body mounting plate; the control arm is connected with a pull rod which can move relative to the control arm; the other end of the pull rod is hinged with the stroke output board that is hinged with the inner main body mounting plate and the outer main body mounting plate; pull rod spacer pins are arranged on the inner main body mounting plate and the outer main body mounting plate. When implementing the parking braking, the theoretical transmission ratio can reach infinite when the control arm and the pull rod are aligned, that is a very strong parking actuating force can be obtained through a very weak operating force, thereby obtaining the parking braking torque that is big enough. The parking braking maneuver mechanism has simple structure and convenient operation, and is suitable for the parking operation of a ground car, a passenger car, etc.
Description
Technical field
The utility model belongs to the automobile parking device, is specifically related to a kind of parking brake control device.
Background technology
Service braking system adopts the vehicle of hydraulic braking, and its emergency brake system generally adopts the muscular energy brake system.For manned vehicle, because vehicle weight is little, Parking requires the gradient little, and braking during standstill requires to be met easily, but the cross country car relatively large for weight, the Parking gradient height that requires, if adopt traditional click parking brake control device, because the parking brake control device transmitting ratio of this structure fixes and be less than normal, when implementing braking during standstill, the motivator that is applied on the drg is also less, is difficult to reach 40% Parking slope requirement of war skill index request.
Summary of the invention
The purpose of this utility model is to provide a kind of increase to act on the parking brake control device of the motivator on the drg, to address the above problem.
The technical solution of the utility model is: parking brake control device, it comprise control arm, can with braking during standstill pull bar bonded assembly stroke output board, it also comprises interior main body adapter plate assembly, outer main body adapter plate.One end of control arm and inside and outside main body adapter plate, outer main body adapter plate are articulated and connected, connect the pull bar of control arm motion relatively on the control arm, the other end of pull bar and stroke output board are hinged, stroke output board and inside and outside main body adapter plate, outer main body adapter plate are hinged, and the main body adapter plate is provided with the pull bar locating dowel pin.
When implementing braking during standstill, with pull bar in line the time, theoretic transmitting ratio can reach infinity at control arm, and the promptly very little actuating force of anticipating just can obtain very large Parking motivator, thereby obtains enough big braking during standstill moment of torsion.This apparatus structure is simple, and control comfort is applicable to cross country car, and Parkings such as manned vehicle are handled.

The specific embodiment
As shown in Figure 1, control arm 1 is articulated and connected by bearing pin 6 and interior main body adapter plate assembly 4 and outer main body adapter plate 17, and articulated structure as shown in Figure 2.Connect the energy pull bar 3 of control arm motion relatively on the control arm 1, control arm 1 inner chamber is provided with adjusts shaft clevis 8, and pull bar 3 is articulated and connected with adjustment shaft clevis 8.Interior main body adapter plate 4, outer main body adapter plate 17 are provided with the locating dowel pin 5 (connection structure such as Fig. 2) of pull bar 3; When locating dowel pin 5 can make control arm 1 and pull bar 3 handle, just cross both linear states.The other end of pull bar 3 and stroke output board 2 are articulated and connected, and stroke output board 2 passes through bearing pin 7 hinged (Fig. 3) with interior main body adapter plate 4, outer main body adapter plate 10.One hole 9 of stroke output board 2 afterbodys is connected with braking during standstill pull bar (not shown) by bearing pin.
Be provided with the delivery stroke adjusting mechanism between control arm and the pull bar, as shown in Figure 4, stroke regulating mechanism comprises the adjustment cover 10 that is located on the control arm 1, the adjustment screw rod 11 that control arm 1 inner chamber is provided with.Adjust screw rod 11 1 ends and adjust cover 10 and is connected, adjust the bulge loop 13 of limiting on the screw rod 11, be provided with between position limiting convex ring 13 and the control arm internal chamber wall and locate collar 14, adjust screw rod 11 like this and can not swing, and rotation is flexible by bearing pin 12.Adjust between cover 10 and the control arm and be provided with antifriction rubber cradle 15.Adjust screw rod 11 other ends and adjust shaft clevis 8, adjust shaft clevis and pull bar 3 and be articulated and connected by bearing pin 16 by being threaded.
When implementing braking during standstill, control arm 1 rotates around bearing pin 6, drives pull bar 3 motions simultaneously, and stroke output board 2 rotates around bearing pin 7 under pull bar 3 effects, moves thereby drive the braking during standstill pull bar.When pull bar 3 touched locating dowel pin 5, brake-applying handle promptly reached lock position.Increase along with output board 2 delivery strokes, the also corresponding increase of the transmitting ratio of four-bar linkage, at control arm 1 with pull bar 3 in line the time, it is infinitely great that theoretic transmitting ratio can reach, the promptly very little actuating force of anticipating just can obtain very large Parking motivator, thereby obtains enough big braking during standstill moment of torsion.
Rotate to adjust cover, screw rod changes with the length that is connected of adjusting shaft clevis, screw rod when adjusting being connected length and shortening of shaft clevis, the delivery stroke change of control arm greatly, otherwise diminish.When chaufeur need be on steeper slope during Parking, need transfer short with the length that is connected of shaft clevis screw rod, it is big that the delivery stroke of brake operation arm becomes, thereby obtain big braking during standstill moment of torsion, can delivery stroke be transferred to suitable value by adjusting cover under general operating mode.In order to avoid the tie system of braking during standstill is damaged owing to being subjected to excessive tension force for a long time.
