Description
Technical field
The utility model relates to mechanical traction field, is specifically related to a kind of front haulage mechanism can drawing platform trailer voluntarily.
Background technology
The front haulage mechanism that some trailers or trailer are waited for bus at present is all common mechanical traction mechanism, ensure the vehicle effectively drawn below, but when car above brakes, car below moves under draw, effectively can not brake, different infringements is all brought to trailer coupling and car itself.
Summary of the invention
In order to solve the problem, the utility model proposes a kind of front haulage mechanism can drawing platform trailer voluntarily, simplicity of design, easy to use, there is buffer action, effectively can also control self to brake, guarantee safety.
In order to reach foregoing invention object, the utility model proposes some technical schemes:
The front haulage mechanism of platform trailer can be drawn voluntarily, described front haulage mechanism is designed with inertia braking device, front haulage mechanism comprises micro-switch, two set pins, draw bar cover, traction guide rod, journal stirrup, pipe link and spring, the sleeve pipe of draw bar cover is drilled with two pin-and-holes, and Front-end Design has eye hitch, traction guide rod leading section is milled with cotter way, traction guide rod leading section injects in draw bar cover, and two set pins all pass through traction guide rod leading section cotter way is inserted in two pin-and-holes on draw bar cover sleeve pipe, draw bar is overlapped traction guide rod can be driven to move together, traction guide rod again can relative movement in draw bar sleeve pipe, traction guide rod apical position has micro-switch, the contact switch head of micro-switch is stretched in draw bar cover sleeve pipe, guide rod can be pulled encounter, traction guide rod rear end connects pipe link by journal stirrup, the pipe link other end is connected on steeraxle, spring housing is contained on traction guide rod, spring at front end withstands on traction pole cap rear end, spring rear end withstands on the boss of traction guide rod rear end design, vehicle be pulled car traction normally travel time, spring elongates state, the contact switch head of micro-switch is not pulled guide rod to be encountered, there is not braking maneuver in vehicle, when tractor truck is braked, tractor truck has stopped, but trailed vehicle because of effect of inertia can continue motion, now spring will compress, traction guide rod can relatively move forward in draw bar cover sleeve pipe, encounter the contact switch head of micro-switch, electric braking signal is sent to motor by micro-switch, realize trailed car brakeing function.
Described set pin is designed with two, is passed in the cotter way of draw bar front end side by side and two ends are fixed on traction pole cap, set pin relative movement in the cotter way of draw bar.
Micro-switch is by the braking mechanism of signal wire (SW) connecting die blocking MPV (Multi-Purpose Vehicle).
The utility model has the advantages that simplicity of design, easy to use, spring can play buffer action, the brake touching this car of micro-switch when draw bar action will start brake, reset under action of the spring, then brake is unclamped, and ensure that safety walking when modular multi-function car is pulled.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of front haulage mechanism of the present utility model.
Fig. 2 is the vertical cross-sectional of front haulage mechanism of the present utility model.
Fig. 3 is the transverse sectional view of front haulage mechanism of the present utility model.
Detailed description of the invention
In order to the present invention is further described, introduce below in conjunction with Figure of description:
Further, looked with reference to Fig. 1-3, the front haulage mechanism of platform trailer can be drawn voluntarily, described front haulage mechanism is designed with inertia braking device, it comprises micro-switch 91, two set pins 92, draw bar cover 93, traction guide rod 94, journal stirrup 95, pipe link 96 and spring 97, the sleeve pipe of draw bar cover 93 is drilled with two pin-and-holes, and Front-end Design has eye hitch 98, draw bar 94 leading section is milled with cotter way, traction guide rod 94 leading section injects in draw bar cover 93, and two set pins 92 all pass through traction guide rod 94 leading section cotter way is inserted in two pin-and-holes that draw bar overlaps on 93 sleeve pipes, making draw bar overlap 93 can drive draw bar 94 to move together, traction guide rod 94 can overlap energy relative movement in 93 sleeve pipes at draw bar again, traction guide rod 94 apical position has micro-switch 91, the contact switch head of micro-switch 91 is stretched and is overlapped in 93 sleeve pipes at draw bar, guide rod 94 can be pulled encounter, traction guide rod 94 rear end connects pipe link 96 by journal stirrup 95, pipe link 96 other end is connected on steeraxle 2, spring 97 is sleeved on traction guide rod 94, spring 97 front end withstands on traction pole cap 93 rear end, spring 97 rear end withstands on the boss 99 of traction guide rod 94 rear end design, vehicle be pulled car traction normally travel time, spring 97 elongation state, the contact switch head of micro-switch 91 is not pulled guide rod 94 to be encountered, there is not braking maneuver in vehicle, when tractor truck is braked, tractor truck has stopped, but trailed vehicle because of effect of inertia can continue motion, now spring 97 will compress, traction guide rod 94 overlaps in 93 sleeve pipes can relatively move forward at draw bar, encounter the contact switch head of micro-switch 91, electric braking signal is sent to motor by micro-switch 91, realize trailed car brakeing function.
When the utility model uses, the eye hitch of front end is connected on the hook below of tractor above, this device rear end is then connected on steeraxle, during normal walking, middle springs is softened state, draw bar front end can not touch micro-switch, there is the change of spot speed a little, spring can play buffer action, once face tractor slowing-down brake, spring is subject to the inertia extruding of tractor truck below, draw bar is made to touch switch, then braking mechanism action starts electric brake, modular multi-function car carries storage battery can be guaranteed effectively to brake, braking mechanism is arranged on one end of drive motor inside trailing wheel.
