Abstract
The utility model belongs to the commercial car class specifically is a commercial car parking device, its characterized in that: including starting drive, parking gear, parking pole, worm wheel, worm, connecting rod, return spring, the parking gear is installed on the derailleur output shaft, and the worm is adorned on starting drive, and the worm wheel cooperatees with the worm, and the worm wheel passes through the connecting rod with the parking pole to be connected, is equipped with a return spring on the parking pole. The utility model discloses during the start -up, starting drive drives the worm and rotates, and worm wheel cooperation worm is rotatory, drives the connecting rod, and the parking pole is backed down, and the output shaft can normally rotate. When needing the parking, close starting drive, under return spring's effort, initial position is got back to again to the parking pole, and with parking gear engagement, the parking function is realized to the dead output shaft of lock.
Description
Technical field
This utility model belongs to commercial car class, specifically a kind of commercial car parking device.
Background technology
At present, commercial car parking generally uses parking brake or gas is stopped, and its principle is all so that driving wheel is locked by locked power transmission shaft.Parking brake is mainly made up of brake bar, bracing wire, arrestment mechanism and return spring, and its shortcoming is in use, and bracing wire is easily deformed, and effectiveness reduces, and parking is existed potential safety hazard by life-time service；Gas is stopped and is mainly made up of air pump, pipeline, gas receiver, brake valve etc., and its shortcoming is that structure is complicated, and cost is high, when arbitrary position is problematic, parking all can be made to lose efficacy, and fault rate is high.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, it is provided that a kind of rational in infrastructure, commercial car parking device that parking efficiency is high, safe and reliable, and it realizes parking by installing parking gear on commercial car output shaft of gear-box.
This utility model is achieved through the following technical solutions:
This utility model one commercial car parking device, it is characterized in that: include starting device, parking gear, parking bar, worm gear, worm screw, connecting rod, return spring, parking gear is arranged on transmission output shaft, worm screw is contained on startup device, worm gear matches with worm screw, worm gear is connected by connecting rod with parking bar, is provided with a return spring on parking bar.
Above-mentioned return spring is fixed on coupling spindle, coupling spindle and parking bar rotatable engagement.
During this utility model original state, parking bar is meshed with parking gear, and locked output shaft reaches parking purpose；When automobile starting, starting device and drive worm screw to rotate, worm gear worm screw rotates, and drives connecting rod, and parking bar is backed down, and output shaft can normally rotate；When needing parking, closing and start device, under the active force of return spring, parking bar comes back to initial position, engages with parking gear, locked output shaft, it is achieved parking function.This utility model is simple and reasonable, dependable performance safety.
Accompanying drawing explanation
Fig. 1 is this utility model parked state structural representation.
Fig. 2 is the non-parked state structural representation of this utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model embodiment is made one to specifically describe:
As shown in Figure 1, 2, a kind of commercial car parking device, including starting device 1, parking gear 9, parking bar 6, worm gear 3, worm screw 2, connecting rod 4, return spring 7, parking gear 9 is arranged on transmission output shaft, and worm screw 2 is contained on startup device 1, and worm gear 3 matches with worm screw 2, worm gear 3, parking bar 6 are connected with connecting rod 4 respectively through bolt 10 and bolt 5, being provided with a return spring 7 on parking bar 6, return spring 7 is fixed on coupling spindle 8, coupling spindle 8 and parking bar 6 rotatable engagement.
During this utility model automobile starting, starting device 1 and drive worm screw 2 to rotate, worm gear 3 rotates, and promotes connecting rod 4, and parking bar 6 is backed down under the promotion of connecting rod 4, separates with parking gear 9；During parking, closing and start device, under the active force of return spring 7, parking bar 6 is pushed back initial position, again engages with parking gear 9, locked output shaft, it is achieved parking function.
