Abstract
The utility model discloses a gear box for small-sized transport vehicles, which comprises a box body, an input shaft which is arranged in the box body, a main shaft which is engageably driven with the input shaft through a gear wheel, an auxiliary shaft which is engageably driven with the main shaft through the gear wheel, a counter shaft which is engageably driven with the auxiliary shaft through the gear wheel and an output shaft which is engageably driven with the center shaft through the gear wheel, a poking sleeve is sleeved on the auxiliary shaft, a gear shift fork is arranged on the poking sleeve, a plurality of grooves are axially opened on the auxiliary shaft, a plurality of claws which are slindingly engaged with the grooves are arranged on the poking sleeve, a plurality of gaps are opened on the inner side of each claw, a through hole is radially opened on the auxiliary shaft, a spring is mounted in the hole, and steel balls which are clamped and engaged with each gap are respectively mounted on both ends of the spring. A shifting mechanism of the gear box has the advantages of simple and compact structure, smooth and fast shifting, little compact and convenient manufacture and maintenance, which has no phenomenon of clamping, gear jumping and gear mixing.
Description
Technical field
The utility model relates to a kind of gearbox that is used for small transporting vehicle.
Background technique
The gear changing mode of tradition gearbox is generally carrier wheel, and its maneuverability pattern is a rotating cam.The shortcoming of this structure is easily to produce impact and clamping stagnation disorderly shelves, trip stop phenomenon when the shift fork handsetting gear moves axially when gear shift, makes gear shift sliding fast.Secondly, this mechanism complexity is not easy to make and maintenance.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, provides that a kind of gearshift mechanism is simple in structure, compact, sliding fast, the no catching phenomenon of gear shift and the gearbox that is used for small transporting vehicle being convenient to make and keep in repair.
The gearbox that is used for small transporting vehicle, it comprises casing, be arranged on the input shaft in the described casing, with described input shaft by the be meshed main shaft of transmission of gear, with described main shaft by the be meshed countershaft of transmission of gear, with described countershaft by the be meshed jack shaft of transmission of gear, with described jack shaft by the be meshed output shaft of transmission of gear, on described countershaft, be with dial sleeve, described dial sleeve is provided with reverse shift fork, on described countershaft, have a plurality of grooves vertically, the a plurality of pawls that are slidingly fitted with described groove are arranged on described dial sleeve, have a plurality of breach in described each pawl inboard, on described countershaft, radially have a through hole, in described hole, spring is housed, be equipped with respectively at the two ends of described spring one with described each breach steel ball of snap-fit mutually.
The gearshift mechanism of this gearbox and the gearshift mechanism that has rotating cam relatively, it is simple in structure, compact, gear shift sliding fast, impact little, no clamping stagnation and trip stop, random shelves phenomenon and be convenient to make and keep in repair.
Description of drawings
Fig. 1 is the gearbox plan view that the utility model is used for small transporting vehicle;
Fig. 2 is a gearbox sectional view shown in Figure 1;
Fig. 3 is the gearshift mechanism partial schematic diagram of gearbox shown in Figure 2.
Embodiment
The utility model specific embodiments (with reference to accompanying drawing) is described as follows:
This gearbox comprise casing 1 be arranged on input shaft 2 in the described casing, with described input shaft by gear be meshed transmission main shaft 3, with described main shaft by gear be meshed transmission countershaft 4, with described countershaft by gear be meshed transmission jack shaft 5, with described jack shaft by gear be meshed the output shaft 6 of transmission, on described countershaft, be with dial sleeve 9, described dial sleeve is provided with reverse shift fork 7.Working principle is when the last a certain shelves gear pair of major and minor axle works, power torque is delivered to input shaft 2 through motor, input shaft 2 is given main shaft 3 transmission of torque by normal engagement bevel gear pair, main shaft 3 is given countershaft 4 transmission of torque by certain grade of engaging tooth wheel set, countershaft 4 is given jack shaft 5 transmission of torque by the constant mesh gear pair, jack shaft 5 is given output shaft 6 transmission of torque by the constant mesh gear pair, and last outputting power drives trailing wheel.
The main feature of this gearbox is its gearshift mechanism.On described countershaft, have a plurality of grooves vertically, be provided with a plurality of pawls that are slidingly fitted with described groove in described dial sleeve inboard, on described each pawl inboard, have a plurality of breach, described breach is a circular arc, on described countershaft, radially have a through hole, in described hole, spring is housed, be equipped with respectively at the two ends of described spring one with described each breach steel ball of snap-fit mutually.Its gear shift principle is to drive reverse shift fork 7 by operating mechanism, and reverse shift fork 7 drives dial sleeve 9 again and moves axially along countershaft, the gear of different gears, reverse gear sprocket wheel 10 is combined, realization speed change and reversing with dial sleeve 9.Its countershaft in axial direction has a plurality of grooves, and the pawl of dial sleeve 9 is stuck in its groove, can axially be free to slide; Countershaft has a through hole on radially, and spring 11 and steel ball 12 are housed in the hole; There are a plurality of circular arc cutaway the pawl inboard of dial sleeve 9, each circular arc cutaway corresponding respectively different gear (comprising reverse gear).When a certain circular arc cutaway of dial sleeve 9 is just in time blocked steel ball 12 in the countershaft through hole, represent that then speed change is a certain gear.Circular arc cutaway has realized gear shift, and has played trip stop, the disorderly effect of shelves of preventing.
Claims (2)
1. the gearbox that is used for small transporting vehicle, it comprises casing, be arranged on the input shaft in the described casing, with described input shaft by the be meshed main shaft of transmission of gear, with described main shaft by the be meshed countershaft of transmission of gear, with described countershaft by the be meshed jack shaft of transmission of gear, with described jack shaft by the be meshed output shaft of transmission of gear, on described countershaft, be with dial sleeve, described dial sleeve is provided with reverse shift fork, it is characterized in that: on described countershaft, have a plurality of grooves vertically, the a plurality of pawls that are slidingly fitted with described groove are arranged on described dial sleeve, have a plurality of breach in described each pawl inboard, on described countershaft, radially have a through hole, in described hole, spring is housed, be equipped with respectively at the two ends of described spring one with described each breach steel ball of snap-fit mutually.
2. gearbox according to claim 1 is characterized in that: described breach is a circular arc cutaway.
