Chinese patent notification number CN201206627Y, a kind of Automotive parking mechanism is disclosed, comprise gearshift, torsion spring, claw, can promote this claw push rod and can with the ratchet of this claw interlock, gearshift comprises shift member, flexible axle and rotating connecting rod, described connecting rod is installed on the fulcrum, this fulcrum is fixed on the described automotive transmission housing, one end of described connecting rod is connected on the described push rod, the other end then is connected with described flexible axle, this flexible axle also is connected with described shift member, on gearshift, be provided with two positioning grooves at least, also fix a location device on the automotive transmission housing, push rod is resisted against on the torsion spring, and claw is rotating to be installed on the automotive transmission housing, one end of torsion spring stretches in the claw, and the other end then is fixed on the automotive transmission housing.This Automotive parking mechanism also can't address the above problem.
The model utility content
The purpose of this utility model is to provide a kind of halting mechanism with Locking Device, to solve the problem that exists in the background technique.
To achieve these goals, the technological scheme of the utility model halting mechanism is: a kind of halting mechanism, comprise catch bar and the ratchet of being located on the case of transmission, one end of described catch bar is hinged with and is subjected to its promotion and rotatable between cog and the sealed ratchet that advances ratchet, described catch bar is provided with latch, described case of transmission be provided with can be sealed with latch the locking pawl.The design philosophy of this technological scheme is: at catch bar latch is set, at case of transmission the locking pawl is set, latch and locking pawl can be mutually locked, thereby stop catch bar to continue to move forward, and have solved the risk that halting mechanism lost efficacy.
As preferably, described locking pawl is articulated on the case of transmission, and the mobile route of described latch is positioned at the plane of rotation of locking pawl.This is intended to rational deployment, interferes in order to avoid produce.
As preferably, an end of described locking pawl is articulated on the case of transmission, and the other end of locking pawl is connected with spring, and the other end of spring is connected on the case of transmission.The purpose that spring is set is to remove when sealed when latch and locking pawl, and spring can make the locking pawl reset.
As preferably, the one side of the close latch of described locking pawl is provided be used to the draw-in groove that holds latch, described spring be connected to the locking pawl with the draw-in groove facing surfaces on.
As preferably, described latch and locking pawl facing surfaces are provided with adaptive inclined-plane.This is intended to make latch to slip into swimmingly to skid off the locking pawl, avoids scratching.
As preferably, described latch is equipped with anti-skidding line on the inclined-plane relative with the locking pawl.
As preferably, the anti-skidding line on described two inclined-planes is adaptive.
As preferably, also be provided be used to the limiting stopper that stops the locking pawl on the described case of transmission.When this structure was preset as latch and just embeds the locking pawl, limiting stopper stopped the locking pawl and rotates.
As preferably, described locking pawl is positioned at the centre of limiting stopper and catch bar.This is intended to rational deployment, avoids interfering.
The beneficial effect of the utility model halting mechanism is: at case of transmission the locking pawl is set, latch and locking pawl can be mutually locked, thereby stop catch bar to continue to move forward, and have solved the risk that halting mechanism lost efficacy.
