Abstract
The utility model discloses an automobile foot brake valve assembly, which comprises a pedal. The pedal is movably connected to an upper cover, and a switch base assembly, an upper valve body and a lower valve body which are fixedly connected are sequentially arranged under the upper cover. The switch base assembly is internally provided with a tappet assembly and a micro-switch assembly. The tappet assembly includes a tappet. The micro-switch assembly includes a micro-switch. A plug used to be connected with an electric eddy current retarder is arranged on the micro-switch. A pressure board is arranged on the tappet. A telescopic rod corresponding to the pressure board is arranged on the micro-switch, and the telescopic rod is arranged downwards against the top face of the pressure board. The utility model realizes an upper-lower expansion without gear shift limits on the micro-switch through the upper-lower moving of the pressure board, thereby the micro-switch assembly outputs signal current without shifts, the foot brake valve assembly can more accurately adjust and control the electric eddy current retarder connected with the foot brake valve assembly, thereby greatly increasing the sensitivity, more securing car driving, and the foot brake valve assembly is quick and flexible in braking without any hysteresis.
Description
Technical field

Background technology
The automobile foot brake valve assembly of at present common band micro-switch mainly contains pedal, loam cake, switch seat assembly, upper valve body and following valve body and forms, the switch seat assembly is fixedly installed in the loam cake below, the upper valve body top is equipped with plunger cap, tappet, composite bush, sliding sleeve and micro-switch assembly in the housing of switch seat assembly.Wherein, the micro-switch assembly is provided with several switch cam, switch cam contacts with plunger cap but is unfixing, the micro-switch assembly is connected with current vortex retarder by the socket that is connected with on the wire harness, thereby can be by the adjusting of foot brake valve being controlled some grades of intensities of current of coupled current vortex retarder, to reach the purpose of safe driving.But such structure has the following disadvantages: because there is gear restriction in the micro-switch assembly, make that the sensitivity of intensity of current of the current vortex retarder that the control of foot brake valve is coupled is low, influence traffic safety.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of automobile foot brake valve assembly, can effectively solve the micro-switch assembly and have the gear restriction, make that the sensitivity of intensity of current of the current vortex retarder that foot brake valve control is coupled is low, influence the problem of traffic safety.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of automobile foot brake valve assembly, comprise pedal, pedal is movably connected in and covers, the loam cake below is provided with the switch seat assembly of captive joint successively, upper valve body and following valve body, be provided with tappet rod complement and micro-switch assembly in the switch seat assembly, tappet rod complement comprises tappet, the micro-switch assembly comprises micro-switch, micro-switch is provided with the plug that is used to connect current vortex retarder, it is characterized in that: tappet is provided with pressing plate, and micro-switch is provided with and the cooresponding expansion link of pressing plate, and expansion link props up the pressing plate end face downwards.
Further, pressing plate comprises the connection pipe in the middle of base plate and the base plate, and plate top surface blocks expansion link, and the connection pipe cross-under makes pressing plate captive joint tappet on tappet.
Further, the relative base plate of connection pipe raises up.
Further, tappet is captiveed joint by riveted with pressing plate.
The utility model is owing to adopted technique scheme, make expansion link on micro-switch, realize the flexible up and down of no gear restriction by moving up and down of pressing plate, make the signal current of the no gear of micro-switch assembly output, make the intensity of current of the coupled current vortex retarder of foot brake valve assembly regulating control more accurate, improved sensitivity greatly, make driving safer, and this foot brake valve assembly braking rapidly flexibly, do not have any hysteresis phenomenon.
