Abstract

The utility model discloses a kind of P to keep off unlock drag-line speed change end component, advantage is the active joint of speed change end component connecting with speed changer and the push rod connecting with wirerope speed change end connector is slip cooperating relationship, it is not fixedly connected, the pilot hole being axially arranged in the middle part of the limited block and active joint that push rod head passes through radially installed, which is slidably matched, carries out axial limiting, in drag-line when in rope, there are default spacing between limited block and the rear wall of pilot hole, active joint can be move freely with shift of transmission, without influencing push rod, wirerope and manipulatable end component；During vehicle transport, under driving status, the displacement of active joint caused by speed changer shakes, also due to the presence of default spacing, limited block on push rod will not be contacted with the rear wall of active joint pilot hole, to which anti-throw-out lever is reversely pulled by active joint, therefore wirerope tensile strength will not due to active joint displacement and reduce, long service life.

Description

P gear unlock drag-line speed change end component

Technical field

The utility model relates to automobile shift control device fields, keep off unlock drag-line speed change end group more particularly, to a kind of P Part.

Background technique

Line traffic control shift type automatic transmission is by the way that the control signal for the gear lever being mounted in driver's cabin to be electrically transmitted to Automatic transmission and control the speed changer.Automatic transmission has park mode, if vehicle cannot because of such as traffic accident Advance or if being difficult to supply electric power because of battery discharge in park mode, only when park mode be forced release when User or maintenance personal can just take the measure such as pulled, and P gear unlock drag-line is exactly the dedicated unit for solving the problems, such as this, For manually controlling speed changer, the park mode of automobile is made to be forced to discharge.

Chinese utility model patent application " a kind of gear that existing P gear unlock drag-line such as publication No. is CN108413030A Disclose a kind of P gear unlock drag-line in position tripper ", the speed change end that P gear unlock drag-line is connect with clutch be it is fixed, Clutch returns to locking position by setting part in speed change end and wirerope pulling.The drag-line of this structure, wirerope can pass through speed change End is moved with the shift of speed changer, interferes the operation of gearbox, wirerope moves back and forth, and will lead to tensile strength Reduction, reduced service life, while wirerope move back and forth the hose that can rub, and cause hose to wear, have much room for improvement.

Utility model content

A technical problem to be solved in the utility model is to provide a kind of P gear unlock drag-line speed change end component, can Do not interfere gearbox to operate normally so that inhaul cable steel wire rope will not due to speed changer relationship and passively move, the drawing of wirerope Therefore stretching intensity will not reduce, long service life.

This P gear unlock drag-line speed change end solves technical solution used by above-mentioned technical problem are as follows: a kind of P gear unlock drag-line Speed change end component, speed change end component include the active joint connecting with speed changer and connect with wirerope speed change end connector Push rod, the head of the push rod axially penetrate in the towing pad of active joint tail portion；The middle part of the active joint is equipped with axial The pilot hole for being arranged and being connected to towing pad, the head radially installed of the push rod have limited block, and the limited block, which protrudes from, to be led It pilot hole and is slidably matched with pilot hole；Drag-line when in rope, there are be used for anti-thrust between the limited block and the rear wall of pilot hole The default spacing that bar is reversely pulled by active joint.

Preferably, the default spacing is 3.5mm~5mm.

As optimal, the default spacing is 4mm.

Compared with prior art, the advantages of this P gear unlock drag-line speed change end component, is that the activity connecting with speed changer connects Head and the push rod connecting with wirerope speed change end connector are slip cooperating relationship, are not fixedly connected, push rod head passes through radial direction The pilot hole being axially arranged in the middle part of the limited block of installation and active joint, which is slidably matched, carries out axial limiting, in drag-line when in rope, There are default spacing between limited block and the rear wall of pilot hole, active joint can be move freely with shift of transmission, without influencing Push rod, wirerope and manipulatable end component；During vehicle transport, under driving status, active joint caused by speed changer shakes Displacement, also due to presetting the presence of spacing, the limited block on push rod will not be contacted with the rear wall of active joint pilot hole, thus Anti- throw-out lever is reversely pulled by active joint；Therefore wirerope will not due to active joint movement and passively move, wirerope Tensile strength be maintained, long service life.

Specific embodiment

The utility model is described in further detail below in conjunction with figure embodiment.

This preferred embodiment is a kind of P gear unlock drag-line as shown in Figure 1, including manipulatable end component 1, movable speed change Hold component 2, wirerope (not indicating in figure), hose 4 and other standing finishes (not indicating in figure).

Wherein, speed change end component 2 is as shown in Fig. 2,3 and 4, including the active joint 21 connecting with speed changer, with wirerope The push rod 22 of speed change end connector connection, limited block 23, screw 24, Pipe protective joint component 25 and dirt-proof boot 26 and active joint 21 neck bush 27.The head of push rod 22 axially penetrates in the towing pad 211 of active joint tail portion 21, and the head of push rod 22 is set For installing radial limited block 23, limited block 23 is fixed by screw 24 and push rod 22 in fluted or hole.Active joint 21 Middle part is axially arranged with the pilot hole 212 for being oriented to limited block 23 being connected to towing pad 211；Drag-line when in rope, limited block There are the default spacing d2 reversely pulled for anti-throw-out lever 22 by active joint 21 between 23 and the rear wall of pilot hole 212, lead Refer to the end hole wall far from speed changer to the rear wall in hole 212；Under the shock effect of vehicle travel process, caused by speed changer The shaking of active joint 21 will not influence push rod 22, so that the wirerope connecting with push rod 22 be kept not to be subjected to displacement, avoid The unconventional decrease of the tensile strength of wirerope, long service life.

In the present embodiment, presetting spacing d2 is preferably 3.5mm~5mm, and optimal is 4mm.It is default that spacing d2 is too short is becoming The vibration of the amplitude range of fast device, speed changer can reversely pull wirerope by active joint 21 and push rod 22, and ideal is not achieved Effect；The default too long difficulty that will increase unlock operation of spacing d2.
