Abstract
The utility model discloses a main reducer of a hybrid bus, and solves the problem that the main reducer of the prior bus can only be connected with single power source and has bad fuel economical efficiency. A hole which can be matched with a bearing seat (3) is formed on a back cover (2); the bearing seat (3) is connected with a driving bevel gear (5) through a bearing, a lug and a dust proof assembly (4); and the other end of the driving bevel gear (5) meshed with a driven bevel gear (6) is connected with the splines of the lug and the dust proof assembly (4), thereby achieving high fuel economy.
Description
Affiliated technical field the utility model relates to a kind of bus retarder, especially relates to a kind of hybrid-power bus main reduction gear of being made up of back axle, bonnet, protecgulum, driven wheel of differential, bearing, drive bevel gear and bead and dust boot assembly.
Background technology is present, the power delivery mode of such two kinds of buses is disclosed on the market: the one, by driving engine through change speed gear box, transmission shaft. again through vehicle bridge to wheel, it is a kind of single bus that power is provided by combustion engine, when bus operates in low-speed big and starting, fuel economy is relatively poor not up to standard with discharging during parking. the second way, be through change speed gear box by high power motor, transmission shaft, again through vehicle bridge to wheel, this bus need set up the special electric power line, and can only on special line, move, influence other vehicle operatings sometimes. along with the rise in price significantly of oil and to more and more strictness of auto emission, utilize the bus of eco-friendly power sources such as natural gas in addition in addition as power fuel, the main deceleration of these buses all adopted following structure: by back axle, bonnet, protecgulum, driven wheel of differential, bearing, drive bevel gear and bead and dust boot assembly are formed, driven wheel of differential by bearing installation in back axle, and be arranged on back axle in the axle be connected, driven wheel of differential and drive bevel gear engagement, drive bevel gear is passed through bearing, bead and dust boot assembly, bearing, bearing seat and protecgulum are arranged on the back axle, thereby bonnet is arranged on the rear of protecgulum. make bus reach high pulling torque the comparatively frequent time marquis of starting, but this structure, easily make the fuel economy of driving engine under the low-speed big operating mode relatively poor, discharge also not up to standard.
The summary of the invention the purpose of this utility model provides a kind of fuel economy under the low-speed big operating mode better and the hybrid-power bus main reduction gear of emission compliance.
For achieving the above object, the utility model hybrid-power bus main reduction gear, by back axle, bonnet, protecgulum, driven wheel of differential, bearing, drive bevel gear and bead and dust boot assembly are formed, driven wheel of differential by bearing installation in back axle, and be arranged on back axle in the axle be connected, driven wheel of differential and drive bevel gear engagement, drive bevel gear is passed through bearing, bead and dust boot assembly, bearing, bearing seat and protecgulum are arranged on the back axle, bonnet is arranged on the rear of protecgulum, on bonnet, have the hole that can dispose bearing seat, bearing seat is connected with drive bevel gear with bead and dust boot assembly by bearing respectively, also is connected with bead and dust boot assembly spline with the other end of driven wheel of differential ingear drive bevel gear.
The axial line of two drive bevel gear should be on same straight line.
After adopting this structure, owing to be connected with driving engine and adjustable frequency motor before and after back axle assembly, when bus was in starting and low speed operating mode, driving engine was in idling mode, is at this moment driven by adjustable frequency motor; When speed is brought up to a certain degree, by engine drive, the advantage that fuel economy is high and discharging is little of performance constant engine operating mode, thereby at this moment electrical motor stops to drive. reach the purpose of fuel economy height and emission compliance, simultaneously, also solve problems such as the rear overhang of bus and transmission inclination angle, made transmission more stable, reduced the transmission fault rate.
The utility model is described in further detail below in conjunction with drawings and Examples for description of drawings.
Accompanying drawing is the main cross-sectional schematic of the utility model hybrid-power bus main reduction gear.
Among the figure: 1. back axle 2. bonnet 3. bearing seats, 4. beads and 7. 8. protecgulums of dust boot assembly 5. drive bevel gear, 6. driven wheel of differentials
The main reduction gear of the utility model hybrid-power bus shown in the specific embodiment accompanying drawing, by back axle 1, bonnet 2, protecgulum 8, driven wheel of differential 6, bearing, drive bevel gear 5 and bead and dust boot assembly 4 are formed, driven wheel of differential 6 by bearing installation in back axle 1, and be connected with axle 7 in being arranged on back axle 1, driven wheel of differential 6 and drive bevel gear 5 engagements, drive bevel gear 5 is passed through bearing, bead and dust boot assembly 4, bearing, bearing seat 3 and protecgulum 8 are arranged on the back axle 1, bonnet 2 is arranged on the rear of protecgulum 8, on bonnet 2, have the hole that can dispose bearing seat 3, bearing seat 3 is connected with drive bevel gear 5 with bead and dust boot assembly 4 by bearing respectively, also is connected with bead and dust boot assembly 4 splines with the other end of driven wheel of differential 6 ingear drive bevel gear 5; The axial line of two drive bevel gear 5 should be on same straight line.
Claims (2)
1. hybrid-power bus main reduction gear, by back axle, bonnet, protecgulum, driven wheel of differential, bearing, drive bevel gear and bead and dust boot assembly are formed, driven wheel of differential by bearing installation in back axle, and be arranged on back axle in the axle be connected, driven wheel of differential and drive bevel gear engagement, drive bevel gear is passed through bearing, bead and dust boot assembly, bearing, bearing seat and protecgulum are arranged on the back axle, bonnet is arranged on the rear of protecgulum, it is characterized in that: on bonnet (2), have the hole that can dispose bearing seat (3), bearing seat (3) is connected with drive bevel gear (5) with bead and dust boot assembly (4) by bearing respectively, also is connected with bead and dust boot assembly (4) spline with the other end of driven wheel of differential (6) ingear drive bevel gear (5).
2. hybrid-power bus main reduction gear according to claim 1 is characterized in that: the axial line of two drive bevel gear (5) should be on same straight line.
