Summary of the invention
In view of this, the present invention, for making up deficiency of the prior art, provides a kind of latching mechanism CNG gas cylinder frame rack device and this vehicle, ensures reliability and other performance.
A kind of CNG gas cylinder frame rack device, comprises column, gas cylinder saddle, gas cylinder bracket, underframe,
Column, at least adopts 2 columns, is with multiple bolt hole, in order to fix with gas cylinder saddle, gas cylinder bracket bolt;
Gas cylinder saddle, gas cylinder saddle comprises the fixing of semi-circular bracket part and the bracket-shaped paired gas cylinder radial direction of gas cylinder, and gas cylinder saddle is also provided with the expenditure end of band screw, and gas cylinder saddle and column are bolted fixing;
Gas cylinder bracket, semicircular in shape, its external part is equipped with screw, is bolted fixing with column;
Underframe, is with multiple bolt hole, is horizontally disposed with and is connected with car, and column and underframe are fixed.
Further, have additional bottom L-type gas cylinder bracket, the long limit of bottom L-type gas cylinder bracket is vertical, and long limit and column are bolted, and are bolted between minor face and underframe.
Further, arrange upright post connecting plate and with bolts between column, upright post connecting plate is parallel with gas cylinder axial direction.
Further, set up vertical connecting panel, connecting panel is bolted column, and bolt connects underframe simultaneously.
Alternatively, set up side and strengthen column, column is strengthened in side and column is adjacent to setting, and column and side are strengthened being bolted between column.
Preferably, be bolted between column and underframe.
Preferably, gas cylinder saddle is one group two settings, and vertical direction arranges many groups, and column adopts 4 or 6, and the horizontal two ends of gas cylinder saddle and column are fixed.
Preferably, gas cylinder saddle is connected with gas cylinder bracket bolt.
Preferably, be bolted between column and underframe, gas cylinder saddle is connected with gas cylinder bracket bolt.
A kind of vehicle, adopts any one CNG gas cylinder frame rack device above-mentioned.
Gas cylinder framework involved in the present invention is with bolts, namely by bolt, the gas cylinder bracket of gas cylinder framework, gas cylinder saddle, column, side is strengthened the parts such as column, connecting panel, underframe and is coupled together.The component universality of different automobile types is high, the amount of parts decreased; Because bolt connects, avoid weld defect, the reliability of gas cylinder framework is high; Latching mechanism gas cylinder framework working accuracy is high, improves efficiency of assembling; Each parts are detachable, maintenance safety (gas cylinder install after, gas cylinder periphery does not allow welding), convenient; Frame assembly deadweight is low, improves vehicular transport efficiency
Above scheme can be found out, version with bolts, while raising product reliability, also can improve the commonality of parts, and maintenance safe ready, can improve the operating efficiency of vehicle especially.
