The wheel hub of every support wheel 4 is provided with magnet stopper 8;
The two ends of U-shaped vehicle frame 2 front end are respectively rectangular frame, and the sidewall of described rectangular frame is vertical; Two support wheels 4 with magnet stopper are installed in the rectangular frame at the two ends of U-shaped vehicle frame 2 front end respectively.
The wheel shaft of described support wheel 4 is made up of interior wheel shaft 6 and felling axe 5, and described felling axe 5 is interior wheel shaft 6 for cannula-like is set in, and the two is free-running fit; The two ends of interior wheel shaft 6 extend the outside, two ends of felling axe 5 respectively, and wherein one end is flange; Felling axe 5 is stepped shaft, and one end is flange, and the other end is bolt; The wheel hub of support wheel 4 is connected on the felling axe 5 of bolt side by bearing, and is fixed by the cooperation of screw bolt and nut; The body of magnet stopper 8 is fixedly connected the flange of felling axe 5, and the armature of magnet stopper 8 is fixedly connected the wheel hub of support wheel 4; The flange end of interior wheel shaft 6 is bolted to connection a sidewall of the rectangular frame of U-shaped vehicle frame one end, and the other end of interior wheel shaft 6 is fixedly connected another sidewall of the rectangular frame of U-shaped vehicle frame one end.
Described bearing is double-row angular contact bal bearing.
Advantageous Effects of the present utility model embodies in the following areas:
1. on the support wheel on reach truck chassis, magnet stopper is installed, solves the problems such as seized, braking liquid seepage, improve the braking reliability of reach truck.The utility model does not use hydraulic brake, there will not be because the reasons such as pollution cause oil circuit to block the seized of generation, the braking liquid seepage phenomenon of the failure that hydraulic part damages, poor sealing causes.
2. the wheel shaft of support wheel adopts the sleeve structure of interior wheel shaft and felling axe, and adopts double-row angular contact bal bearing to be arranged on support wheel, solves the problem of bearing earlier period damage, and easy for installation, good manufacturability.Double-row angular contact bal bearing can bear the larger footpath based on Radial load, axially two-way joint load and moment load, two the putting of use two tapered roller bearing dos-à-doss can be avoided the installation play brought is installed is difficult to adjustment problem, solve the bearing earlier period damage problem of car load about 15%.
3. electromagnetic braking support wheel of the present utility model adopts bolts assemblies, safeguards simple and convenient.

Detailed description of the invention
Below in conjunction with accompanying drawing, by embodiment, the utility model is further described.
See Fig. 1 and Fig. 2, the reach truck chassis assembly with electromagnetic braking support wheel comprises U-shaped vehicle frame 2, trailing wheel 1, drive motor and two support wheels; The open end of U-shaped vehicle frame 2 is front end, and closed end is rear end; Trailing wheel 1 is drive wheel, is connected to drive motor; Trailing wheel 1 is fixedly installed in the middle part of U-shaped vehicle frame 2 rear end by drive wheel bracket 11, and two support wheels are installed on the two ends of U-shaped vehicle frame 2 front end respectively.
See Fig. 2, U-shaped vehicle frame 2 both sides are respectively left branch leg 9 and right supporting leg 10, the two ends of left branch leg 9 and right supporting leg 10 are respectively rectangular frame, the sidewall of rectangular frame is vertical, wherein corresponding channel-section steel 13 sidewall and lateral wall 12 are support wheel 4 assembly wall, channel-section steel 13 sidewall and lateral wall 12 offer mounting hole respectively, sees Fig. 3 and Fig. 4.
See Fig. 6, the wheel shaft of support wheel 4 is made up of interior wheel shaft 6 and felling axe 5, and felling axe 5 is on cannula-like is sleeved on interior wheel shaft 6, and the two is that two ends H7/f7 small―gap suture coordinates, and middle part wide arc gap coordinates.The two ends of interior wheel shaft 6 extend the outside, two ends of felling axe 5 respectively, and wherein one end is flange; Felling axe 5 is stepped shaft, and one end is flange, and the other end is bolt; The wheel hub of support wheel 4 is connected on the felling axe 5 of bolt side by bearing 7, and bearing 7 is double-row angular contact bal bearing, and is fixedly connected with by the cooperation of the screw bolt and nut of felling axe 5 one end.The body of magnet stopper 8 is fixedly connected the flange of felling axe 5, and the armature of magnet stopper 8 is fixedly connected the wheel hub of support wheel 4; The flange end of felling axe 5 is bolted to connection channel-section steel 13 sidewall of U-shaped vehicle frame one end, the flange end of interior wheel shaft 6 is bolted to connection channel-section steel 13 sidewall of U-shaped vehicle frame one end, see Fig. 5, the other end of interior wheel shaft 6 is fixedly connected another sidewall of the rectangular frame of U-shaped vehicle frame one end.
