Accompanying drawing explanation
Fig. 1 is the profile schematic diagram of an embodiment of the present utility model;
Fig. 2 is the cutaway view of main gear primary speed-down part in Fig. 1;
Fig. 3 is the cutaway view of taking turns limit double reduction part in Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1,2,3, the utility model is mainly comprised of double reduction and Wet-type paper friction disc brake.
Shown in Fig. 2, described primary speed-down is that main gear screw bevel gear slows down, it mainly comprises a pair of spiral bevel gear and differential assembly, and wherein initiatively spiral bevel gear 2 is connected in bracket 5 by bearing, and large spiral bevel gear 3 and differential assembly 10 are connected and fixed by bolt; Described differential assembly is comprised of finishing bevel gear cuter 7, bevel gear shaft 8, axle side gear 4 and differential casing 6, and finishing bevel gear cuter 7 is radially positioned in differential casing 6 by bevel gear shaft 8, and axle side gear 4 has semiaxis 9 by spline joint; Main working process is: be connected with complete machine gear box output end mouth with the flange 1 of active spiral bevel gear by spline joint, the transmission of power that during work, initiatively spiral bevel gear is come change speed gear box input is to large spiral bevel gear, now large spiral bevel gear drives whole differential assembly motion, by transmission of power, to passing through on the semiaxis 9 of spline joint with axle side gear, primary speed-down increases have been turned round.
Shown in Fig. 3, described double reduction is planetary gear speed-reduction, one internally toothed annulus 18 passes through spline joint with internally toothed annulus support 14, internally toothed annulus support and hub carrier 12 pass through spline joint, hub 13 is located by connecting on hub carrier by bearing 20, and planetary wheel carrier 25 is bolted to connection with hub; On described planetary wheel carrier, hot jacket has one group of planet wheel spindle 24, and satellite gear 23 is installed on axle; The sun wheel 19 of hot jacket on semiaxis 9 and satellite gear 23 engagements; Main working process is, the transmission of power that semiaxis 9 passes over primary speed-down is to sun wheel 19, thereby sun wheel drives whole planetary wheel carrier and hub to rotate transmission of power to satellite gear and internally toothed annulus again, drives complete machine walking, and double reduction increases have been turned round.
Described Wet-type paper friction disc brake adopts domestic Wet-type paper friction lining and 16 hydraulic brakings of steel disc assembly, wherein steel disc assembly 16 and internally toothed annulus 18 are fixed by spline joint, paper-base friction wafer and friction disc support 22 pass through spline joint, and are connected with semiaxis together.
Described paper-base friction wafer one side is provided with piston 15 and retracing spring 21, is provided with and the confined space of braking oil nozzle 11 and being communicated with between described internally toothed annulus support and piston 15; Described paper-base friction wafer opposite side is provided with bearing plate 17.
Drive axle drag described in the utility model, it abandons the caliper disc brake of original driving bridge for engineering machinery, adopt domestic Wet-type paper friction lining and 16 hydraulic brakings of steel disc assembly, wherein steel disc and internally toothed annulus are fixed by spline joint, paper-base friction wafer and friction disc support 22 spline joints, during work, paper-base friction wafer rotates with semiaxis with friction disc support.When complete machine need to be braked, brake-pressure oil is pressed into the confined space between internally toothed annulus support and piston 15 by braking oil nozzle 11, thereby promote piston and friction lining motion, because being adjacent to rapidly friction lining, the obstruction of bearing plate 17 produces friction force to reach braking effect, after braking successfully, only need take-off the brake device to make piston reset by the application force of spring 21, complete machine can normally travel.
