Abstract
The utility model relates to a two-way braking device which is improved on the basis of existing braking devices. In the utility model, the front end of a brake rod is provided with an oblique groove, a vehicle frame on the front part of the brake rod is fixed with a rotating shaft which is sheathed and provided with a rotating shaft pipe sleeve which is fixed with a traction hold, and a pipe sleeve corresponding to the brake rod is fixed with a cam. Because when the traction hold is put down or upwards turned, the cam can all support the brake rod and backwards move between the cam and the brake rod; when the traction hold is horizontally placed, the brake rod is reset under spring action, the utility model realizes two-way braking and effectively prevents accidents caused by the move of automobiles under outside force action because of the improper placement of the traction hold. The utility model has the advantages of simple structure, high safety and low cost.
Description
The utility model relates to a kind of brake equipment, a kind of bidirectional braking device that is used for non-motor-driven loading transtainer of more specifically saying so.
At present, the brake equipment that is used for non-motor-driven loading transtainer is unidirectional, promptly otherwise traction downwards the time, trailer is in braking mode; When the traction handle made progress, trailer was in braking mode; The trailer of this one-way brake, if since traction not being placed on braking position, trailer moves trailer and causes the accident generation under the effect of external force.
The purpose of this utility model provides a kind of no matter mop can both make vehicle be in the bidirectional braking device of braking mode up or down.
The purpose of this utility model can realize in the following manner: a kind of bidirectional braking device: include the orienting sleeve that is fixed on the vehicle frame and be sleeved on brake rod in the orienting sleeve, the tape guide key, the rear portion of brake rod is fixed with stop collar with bearing pin, the rear end of brake rod is fixed with guide pipe, spring housing is contained on the guide pipe, the front end of described brake rod has oblique groove, be fixed with rotating shaft on the brake rod front frame, be set with the rotating shaft pipe box on it, be fixed with the traction handle on the pipe box, be fixed with cam on the pipe box relative with brake rod; Described cam has two projectioies, and the thickness of upside projection can block in the groove of brake rod, and the position of projection is on the cam: when the traction handle put down, the downside projection was moved after heading on brake rod; Traction is when upwards digging, and the upside projection is moved after being stuck in and making brake rod in the groove of brake rod.
The utility model compared with prior art has following advantage: simple in structure, the bi-directional braking performance is good, i.e. traction put down or on when turning over, vehicle can both be realized braking, thereby can avoid vehicle to have an accident under external force.Safe and reliable when this device uses in addition, cost is low.
Description of drawings:
Accompanying drawing 1 is a structural front view of the present utility model.
Accompanying drawing 2 is partial views of the birds-eye view of Fig. 1.
The utility model is described in further detail with reference to the accompanying drawings:
With reference to accompanying drawing 1, shown in 2: a kind of bidirectional braking device, include the orienting sleeve 5 that is screwed on vehicle frame 9, be set with brake rod 8 in the orienting sleeve 5, be screwed feather key 10 on the cylinder of brake rod 8, feather key 10 matches with keyway on the orienting sleeve 5, brake rod 8 can only be moved vertically, and can not rotate, the front end of brake rod 8 has oblique groove, the rearward end of brake rod 8 has pin shaft hole, with bearing pin 7 stop collar 6 is fixed on the brake rod 8 on it, and the rear end of brake rod 8 is fixed with guide pipe 12, spring 11 is sleeved on the guide pipe 12, the other end of guide pipe 12 brake system of ining succession.On the vehicle frame 9 of brake rod 8 front portions, be mounted with rotating shaft 4, be set with rotating shaft pipe box 2 in the rotating shaft 4, pipe box 2 can rotate mutually with rotating shaft 4, be fixed with traction on the pipe box 21, with brake rod 8 corresponding pipe boxes 2 on be fixed with cam 3, two projectioies are arranged on the described cam 3, wherein the projection of upside can be stuck in the groove of brake rod 8, when traction was put down 1, the downside projection was moved after heading on brake rod 8; When traction was upwards dug 1, cam 3 upside projectioies were moved after being stuck in and making brake rod 8 in the groove of brake rod 8, thus the realization bi-directional braking.And when drawing 1 level, cam 3 does not contact with brake rod 8, and brake rod 8 makes vehicle be in non-braking mode under the effect of spring 11.
