Abstract

This utility model is specially a kind of electric motor car two shift transmissions, solves existing electric motor car and there is the problem that cannot meet the use requirement of Coal Transportation pot motor.Electric motor car two shift transmissions, including case of transmission, power shaft arranged in parallel and output shaft it is provided with in transmission case body, driving gear it is fixed with on power shaft, be cased with on output shaft with drive gear to engage and left and right distribution high gear gear and low gear gear, it is fixed with toothholder on output shaft between high gear gear and low gear gear, it is cased with the tooth set engaging and can engaging with high gear gear and gear, low shift on toothholder, and is provided with Double-conical-surface lock ring type base steel sprayed molybdenum lock unit on high gear gear and low gear gear.This utility model reasonable in design is reliable, not only shifts gears light, reliable in quality, and precision is high, noise is low, can meet the use requirement of pot motor, has simple in construction, the easy to process and advantage of low cost.

Description

Electric motor car two shift transmissions
Technical field
This utility model relates to variator, a kind of is matched with colliery system transport people, the electric motor car of thing Use two shift transmissions.
Background technology
Along with national requirements for environmental protection is increasingly stricter, electric motor car develops into a kind of trend and trend, current domestic majority Colleges and universities, R&D institution, enterprise are all devoted to electric motor car and the exploitation of the parts that match thereof, but electronic vehicular transmission is still in sky White state.
Summary of the invention
This utility model cannot meet what the use of Coal Transportation pot motor required to solve existing electric motor car existence Problem, it is provided that a kind of electric motor car two shift transmissions.
This utility model adopts the following technical scheme that realization: electric motor car two shift transmissions, including case of transmission, It is provided with power shaft arranged in parallel and output shaft in transmission case body, power shaft is fixed with driving gear, output shaft On be cased with and drive gear to engage and the high gear gear of left and right distribution and low gear gear, defeated between high gear gear and low gear gear It is fixed with toothholder on shaft, toothholder is cased with the tooth set engaging and can engaging with high gear gear and gear, low shift, and high gear Being provided with Double-conical-surface lock ring type base steel sprayed molybdenum lock unit on gear and low gear gear, the right-hand member connection of output shaft has hand braking Device.
During operation, after power transmission to power shaft, drive and drive gear and the high gear gear engaged and low gear gear Rotate, make high gear gear and toothholder engage with tooth set now by fluctuation tooth set, or low gear gear and toothholder engage with tooth set, Under Double-conical-surface lock ring type base steel sprayed molybdenum lock unit effect, after carrying out high to low gear switching, power is transmitted to output shaft, and pass through Hand brake brakes, and overcomes existing electric motor car existence and cannot meet asking of Coal Transportation pot motor use requirement Topic.
This utility model reasonable in design is reliable, not only shifts gears light, reliable in quality, and precision is high, noise is low, can Meet the use requirement of pot motor, there is simple in construction, the easy to process and advantage of low cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-case of transmission, 2-power shaft, 3-output shaft, 4-drives gear, 5-high gear gear, 6-low gear gear, 7-toothholder, 8-tooth set, 9-Double-conical-surface lock ring type base steel sprayed molybdenum lock unit, 10-hand brake.
Detailed description of the invention
Electric motor car two shift transmissions, including case of transmission 1, are provided with arranged in parallel in case of transmission 1 Power shaft 2 and output shaft 3, power shaft 2 is fixed with driving gear 4, output shaft 3 is cased with engage and left and right with driving gear 4 The high gear gear 5 of distribution and low gear gear 6, the output shaft 3 between high gear gear 5 and low gear gear 6 is fixed with toothholder 7, tooth It is cased with the tooth that engages and can engage with high gear gear 5 and gear, low shift 6 on seat 7 and overlaps 8, and high gear gear 5 and low gear gear 6 On be provided with Double-conical-surface lock ring type base steel sprayed molybdenum lock unit 9, the right-hand member of output shaft 3 connects hand brake 10.
